There’s an awful lot of prejudice against Cannondale’s, especially from those of us old enough to remember the frames they made in the mid-90’s. Even back then they had a lifetime warranty and I seem to recall that one particular frame had a 100% failure rate.
Personally I’ve always regarded Cannondale as overpriced, but they never shy away from interesting design and recent bikes seem to have had great reviews.
But I can see why you might be getting a little bored of the Turner. As Mrtrotter says the handling is very neutral, but I am still amazed after three years just what my Flux will let me get away with.
Ride the ‘Dale though and see what you reckon, single pivots definitely have their own charms!
